![]() While these modules are free as in beer, they are not free as in speech and thus are not included by some distributions because the maintainers feel it "taints" the kernel by providing non-free software. nVidia, ATI, among others) do not provide the source code but rather they build their own modules and compile the needed. The Linux Kernel Exists As A File Named By reuroq Question: Which two filesystems below do not perform journaling Answer: ext2, VFAT Question: The Linux kernel exists as a file named: Answer: vmlinuz Question: When a user interacts with his computer, he interacts directly with the kernel of the computer’s operating system. You can use the dpath function to regenerate a human-readable path name for a struct path like file->fpath. Since the operation is atomic, there is absolutely no period. So to do this you would create a new file under a different name, and then call rename to rename the temporary file as the one you want to replace. ![]() The rename system call is an atomic operation. (After the kernel has been booted, the root is 'pivoted' to the normal root and the boot time root is usually called /boot in the run-time filesystem. Once all applications have closed the old file, then its actually unallocated on the disk. That's probably called /boot by the time the system is fully loaded. In Linux, how can I get the filename from the 'struct file' structure, while stepping thru the kernel with kgdb Ask Question Asked 10 years ago Modified 1 year, 11 months ago Viewed 19k times 11 I'm trying to view the filename via kgdb, so I cannot call functions and macros to get it programatically. Third party and closed source modules are available in some distributions, like Ubuntu, and may not be installed by default because the source code for the modules is not available. Just not in a plain-text form, but parsed into objects that are more useful for kernel operation, namely a chain of dentry structures, and the vfsmount structure pointing to the root of the current subtree. The path that the kernel reports that it was loaded from is relative to the root as it was at the time the kernel was loaded. Because of their modular nature you can easily customize your kernel by setting modules to load, or not load, during startup with the menuconfig command or by editing your /boot/config file, or you can load and unload modules on the fly with the modprobe command. ko and are typically stored in the /lib/modules directory. A module typically adds functionality to the base kernel for things like devices, file systems, and system calls. Kernel: it is the primary component of Linux and is typically in charge of all important OS tasks including process management, device management, etc.
